Unfortunately, I really shouldn't run without nvnet so if thats a known issue then its not in google ;) (If its highly likely to be related I can try it this week; it means I end up downing my wlan..) It doesn't take long - couple of days at most - before there are a couple of oopses in the logs (decodes below) and swap usage begins climbing without ever being reclaimed. (Similar problems occurred in 2.4.23-pre5, with the added bonus of processes cratering out in D state and never going away.) These are from an unpatched 2.4.23-pre8: [10:49:24] [dis@floyd] $ uptime 10:49:26 up 2 days, 30 min, 2 users, load average: 1.56, 1.57, 1.49 [10:49:26] [dis@floyd] $ free total used free shared buffers cached Mem: 256932 254736 2196 0 13804 64932 -/+ buffers/cache: 176000 80932 Swap: 2000084 443248 1556836 [10:49:27] [dis@floyd] $ cat /proc/slabinfo slabinfo - version: 1.1 kmem_cache 62 72 108 2 2 1 ip_conntrack 255 804 320 67 67 1 fib6_nodes 12 112 32 1 1 1 ip6_dst_cache 13 20 192 1 1 1 ndisc_cache 3 30 128 1 1 1 tcp_tw_bucket 6 30 128 1 1 1 tcp_bind_bucket 72 448 32 4 4 1 tcp_open_request 0 30 128 0 1 1 inet_peer_cache 3 59 64 1 1 1 ip_fib_hash 13 112 32 1 1 1 ip_dst_cache 1850 1920 192 96 96 1 arp_cache 22 30 128 1 1 1 blkdev_requests 3072 3090 128 103 103 1 journal_head 1468 5236 48 55 68 1 revoke_table 3 250 12 1 1 1 revoke_record 0 112 32 0 1 1 dnotify_cache 0 0 20 0 0 1 file_lock_cache 20 42 92 1 1 1 fasync_cache 0 0 16 0 0 1 uid_cache 12 112 32 1 1 1 skbuff_head_cache 225 780 192 39 39 1 sock 240 336 896 83 84 1 sigqueue 0 29 132 0 1 1 kiobuf 0 0 64 0 0 1 cdev_cache 16 118 64 2 2 1 bdev_cache 5 59 64 1 1 1 mnt_cache 13 59 64 1 1 1 inode_cache 6821 6825 512 975 975 1 dentry_cache 5297 5310 128 177 177 1 filp 2374 2400 128 80 80 1 names_cache 0 2 4096 0 2 1 buffer_head 17182 17790 128 592 593 1 mm_struct 76 90 128 3 3 1 vm_area_struct 3811 3930 128 131 131 1 fs_cache 73 118 64 2 2 1 files_cache 74 81 448 9 9 1 signal_act 89 90 1344 30 30 1 size-131072(DMA) 0 0 131072 0 0 32 size-131072 0 0 131072 0 0 32 size-65536(DMA) 0 0 65536 0 0 16 size-65536 1 1 65536 1 1 16 size-32768(DMA) 0 0 32768 0 0 8 size-32768 4 4 32768 4 4 8 size-16384(DMA) 0 0 16384 0 0 4 size-16384 8 8 16384 8 8 4 size-8192(DMA) 0 0 8192 0 0 2 size-8192 2 2 8192 2 2 2 size-4096(DMA) 0 0 4096 0 0 1 size-4096 150 201 4096 150 201 1 size-2048(DMA) 0 0 2048 0 0 1 size-2048 63 78 2048 35 39 1 size-1024(DMA) 0 0 1024 0 0 1 size-1024 85 88 1024 22 22 1 size-512(DMA) 0 0 512 0 0 1 size-512 146 152 512 19 19 1 size-256(DMA) 0 0 256 0 0 1 size-256 517 525 256 35 35 1 size-128(DMA) 0 0 128 0 0 1 size-128 1810 1830 128 61 61 1 size-64(DMA) 0 0 64 0 0 1 size-64 3467 3481 64 59 59 1 size-32(DMA) 0 0 64 0 0 1 size-32 1612 2301 64 39 39 1 [10:51:34] [dis@floyd] $ lsmod Module Size Used by Tainted: P ipt_mark 472 46 ipt_state 568 0 (unused) ipt_mac 696 2 ip_nat_irc 2192 0 (unused) ip_conntrack_irc 3056 1 ip_conntrack_ftp 4016 1 (autoclean) ip_nat_ftp 2864 0 (unused) iptable_filter 1772 1 iptable_mangle 2168 1 ipt_LOG 3416 0 (unused) ipt_TOS 1048 0 (unused) ipt_REJECT 3544 0 (unused) ipt_MARK 792 3 ipt_MASQUERADE 1464 8 ipt_REDIRECT 824 4 iptable_nat 16014 3 [ip_nat_irc ip_nat_ftp ipt_MASQUERADE ipt_REDIRECT] ip_conntrack 19908 4 [ipt_state ip_nat_irc ip_conntrack_irc ip_conntrack_ftp ip_nat_ftp ipt_MASQUERADE ipt_REDIRECT iptable_nat] ip_tables 12288 14 [ipt_mark ipt_state ipt_mac iptable_filter iptable_mangle ipt_LOG ipt_TOS ipt_REJECT ipt_MARK ipt_MASQUERADE ipt_REDIRECT iptable_nat] nfsd 72880 8 (autoclean) lockd 50928 1 (autoclean) [nfsd] sunrpc 68736 1 (autoclean) [nfsd lockd] sd_mod 11084 0 (autoclean) (unused) sg 27516 0 (autoclean) (unused) sr_mod 15576 0 (autoclean) (unused) scsi_mod 85760 3 (autoclean) [sd_mod sg sr_mod] ide-cd 32032 0 (autoclean) cdrom 28320 0 (autoclean) [sr_mod ide-cd] hid 21572 0 (unused) usbmouse 2264 0 (unused) ehci-hcd 17260 0 (unused) nvnet 26272 1 ipv6 167124 -1 tulip 40608 1 crc32 2880 0 [tulip] usbkbd 3640 0 (unused) usb-ohci 18888 0 (unused) usbcore 62892 1 [hid usbmouse ehci-hcd usbkbd usb-ohci] Crash dump and config attached - if you need anything else let me know.
